• Lines of Symmetry, [4.G.A.3] find the lines that fold a shape onto itself

Plan a useful review session

Ask your child to explain one example before starting a full set. If multiplication is the difficulty, review place value and multiplication facts before moving to longer products. For fraction comparison, revisit equivalent fractions and benchmarks such as one-half.

Work on a manageable group of problems, then discuss one mistake. Ask, “What does each number represent?” and “How could you check the answer?” Return to the same skill later with a fresh problem. Adjust the session to the learner rather than treating a fixed number of minutes as a requirement.

Use skill worksheets alongside official CAASPP practice

California’s Smarter Balanced assessment system uses computer-based tests and performance tasks in mathematics. These skill worksheets support paper-based review; they do not reproduce the full online assessment experience or establish readiness for every tested task.

For the official assessment overview, see the California Department of Education’s Smarter Balanced information. Use the official Smarter Balanced practice and sample-question page to find resources for learning the test format. Follow your school’s directions for testing dates and available supports.

Review the method before more practice

When fraction calculations or word problems are difficult, start with a worked explanation:

• How to add and subtract fractions with like denominators
• How to solve multi-step word problems

Compare optional Grade 4 books

For families considering a longer study resource, review the current product descriptions and previews for Mastering Grade 4 Math and Mastering Grade 4 Math Word Problems. Match the topic coverage and format to the help your child needs.

You can also review the California CAASPP Grade 4 Math Preparation Bundle for its current included resources and purchase options. The worksheets above remain a separate free starting point.

Questions about using this page

How do I choose a worksheet?

Use the skill headings to match your child’s current lesson. Begin with one example and check understanding before assigning a longer practice set.

Do I need an email or account to choose a worksheet?

No. Choose an existing PDF link from the list to open the resource directly.

Are these worksheets the same as the official CAASPP practice test?

No. These are skill-review resources. Official Smarter Balanced practice resources help students become familiar with assessment formats and online tools.
